telnetting to SMTP server

    General discussion

  • My SMTP is configured in one of the server with 10.10.10.53. I had one oracle database server which is oushing mail from ERP appliaction to the user using this internal SMTP. Now we are trying to upgrade the database sever from Windows servrer 2003 to windiws 2008 R2.

    In the new test server we cannot able to telnet to port 25 of 10.10.10.53 . The connection canot be able to establish.

    I already exluded the port in the firewallfor both incoming and outgoing traffic. What else will be the problem blocking the communication to SMTP server fro mnew test database server

  • On the server itselft, does you can telnet localhost 25 ? In netstat -ano do you see the port 25 open ?

    In you IIS manager' console, can you see the SMTP' service ?

    Yes port 25 is in lisytening moe when check through netstat -ano on the SMTP server. Default VIRtual SMTP is there in the IIS of this server.

    Also I can telnet to port 25 from two other servers.

    any possible solution for the above query. I can telnet to port 25 onmy SMTP server from another new server. New server is Windows 2008 R2 and the SMTP server is Windows 2003 Standard. I can possible to telnet tp this from some of my existing Windows 2003 server whcih are configure to send mails from different application on it. So SMTP is working fine and port 25 is opened in it. IS it anything to do with the Windows 2008 and 2003 compatability.

    requesting a reply fromall of you

  • It was Mcafee antivirus creating the problem . when I disabled the access protection it was fine.

    Same way you can exclude to get the conenction proper to the smtp server.
